Description

This function returns the attribute format (attr) of an attribute in the vertex attribute format table (VAT). Each attribute format describes the data type (type), number of elements (cnt), and, if necessary, a fixed point format (frac). The VAT can use eight vertex formats. The vertex format describes the format of all attributes in a vertex. Use the GXSetVtxAttrFmt function to describe an attribute format.
